Description

Technical Field

[0001] This utility model belongs to the field of granulator technology, and in particular relates to a granulator cylinder for a granulator. Background Technology

[0002] In the production of alloy granulated products, a granulator is used for granulation. The granulation cylinder of the granulator is one of its main components. Regarding the granulation cylinder of a granulator, a search of existing technology reveals that Chinese utility model patent CN203355687U discloses a granulator, such as... Figure 1 As shown, it mainly includes a granulation channel a, a bottom cylinder e above the granulation channel a, a granulation cylinder b integrally connected above the bottom cylinder e, an extension cylinder c above the granulation cylinder b, granulation holes d on the granulation cylinder b and the extension cylinder b, and rotating blades and pressing blades inside the granulation cylinder.

[0003] In the prior art, the granulation cylinder of a granulator with a similar technical solution to the above has been found to have some shortcomings in actual implementation: the uppermost end of the extension cylinder above the granulation cylinder is also provided with a granulation hole. When the material is put into the granulation cylinder, the material powder is easy to flow directly out of the granulation hole, causing material spillage and incomplete granulation. Utility Model Content

[0004] In view of the deficiencies and defects in the existing technology, the purpose of this utility model is to provide a granulation cylinder for a granulator, which solves the problem that in the existing granulator cylinder, the uppermost end of the extension cylinder above the granulation cylinder is also provided with a granulation hole, and when the material is put into the granulation cylinder, the material powder can easily flow directly out of the granulation hole, causing material spillage and incomplete granulation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a granulation cylinder of a granulator, including a granulation channel, a bottom cylinder, an intermediate cylinder, rotating blades and pressing blades above the granulation channel, the intermediate cylinder having multiple granulation holes, at least one intermediate cylinder detachably connected above the bottom cylinder, and a top cylinder detachably connected above the intermediate cylinder, the top cylinder being trumpet-shaped, the upper end of the bottom cylinder being closed, a motor being installed inside the bottom cylinder, the output shaft of the motor extending into the intermediate cylinder, and the rotating blades and pressing blades being connected and fixed to the output shaft of the motor inside the intermediate cylinder, the pressing blades including three fan blades connected together, each fan blade being inclined downward on the side closest to the rotation direction.

[0006] As a further improvement of this utility model, the bottom cylinder and the middle cylinder, and the middle cylinder and the top cylinder are detachably connected by flanges.

[0007] As a further improvement of this utility model, the three blades of the pressing blade are made as one piece, and the middle of the pressing blade is detachably sleeved on the output shaft of the motor. A threaded section is provided above the output shaft of the motor, and a nut is threadedly connected to the threaded section. The nut presses on the pressing blade.

[0008] As a further improvement of this utility model, the rotating blade is detachably sleeved on the output shaft of the motor.

[0009] As a further improvement of this utility model, the inner sides of the upper and lower ends of the intermediate cylinder are provided with inwardly protruding rings.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1. By setting a bottom cylinder, an intermediate cylinder, and a top cylinder, with a granulation hole on the intermediate cylinder and a trumpet-shaped top cylinder, the top cylinder plays a certain transition role when the granulation material is put into the top cylinder, preventing the granulation material from falling out of the granulation hole before granulation, thus avoiding the problems of material leakage and incomplete granulation.

[0012] By setting the pressing blades as three fan blades, each fan blade has a structure that is inclined downward on the side closest to the direction of rotation, so that the pressing blades can easily cut into the granulation material when the granulation material is rotating, thus reducing resistance.

[0013] 2. By using flanges to detachably connect the bottom cylinder and the intermediate cylinder, and the intermediate cylinder and the top cylinder, the intermediate cylinder and the top cylinder can be easily disassembled. This not only facilitates the cleaning and maintenance of the intermediate cylinder, but also facilitates the disassembly and installation of the rotating blades and the pressing blades.

[0014] 3. By making the three blades of the pressing blade as one piece, the middle of the pressing blade is detachably sleeved on the output shaft of the motor, thus facilitating the disassembly of the pressing blade. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 2-3 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0021] For ease of description, the coordinate system is defined as follows: Figure 2 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0022] This utility model discloses a granulation cylinder for a granulator, used in a granulator. Other components and technical principles of the granulator are the same as in the prior art. (Refer to...) Figure 2 and Figure 3 A pelletizing cylinder for a pellet mill includes a pelletizing channel 1. Above the pelletizing channel 1 are a bottom cylinder 2, an intermediate cylinder 3, rotating blades 4, and pressing blades 5. The technical structure of the pelletizing channel 1, rotating blades 4, and pressing blades 5, and the principle of the pellet mill, can be found in patent publication number CN203355687U.

[0023] The intermediate cylinder 3 is provided with multiple granulation holes 6. At least one intermediate cylinder 3 is detachably connected to the top of the bottom cylinder 2, and a top cylinder 11 is detachably connected to the top of the intermediate cylinder 3. The top cylinder 11 is trumpet-shaped. Specifically, the bottom cylinder 2 and the intermediate cylinder 3, and the intermediate cylinder 3 and the top cylinder 11 are detachably connected by flanges 7. By detachably connecting the bottom cylinder 2 and the intermediate cylinder 3, and the intermediate cylinder 3 and the top cylinder 11 by flanges 7, the intermediate cylinder 3 and the top cylinder 11 can be easily disassembled. This not only facilitates the cleaning and maintenance of the intermediate cylinder 3, but also facilitates the disassembly and installation of the rotating blades 4 and the pressing blades 5.

[0024] The bottom cylinder 2 is closed at the top and contains a motor. The output shaft of the motor extends into the intermediate cylinder 3, and the rotating blade 4 and the pressing blade 5 are connected and fixed to the output shaft inside the intermediate cylinder 3. The pressing blade 5 includes three fan blades 51 connected together, and each fan blade 51 is inclined downward on the side closest to the rotation direction. In addition, the inner sides of the upper and lower ends of the intermediate cylinder 3 are provided with inwardly protruding rings 10.

[0025] like Figure 3 As shown, the three blades 51 of the pressing blade 5 are integrally manufactured. The middle blade of the pressing blade 5 is detachably mounted on the output shaft of the motor. A threaded section 8 is provided above the output shaft of the motor, and a nut 9 is threadedly connected to the threaded section 8. The nut 9 presses against the pressing blade 5. The rotating blade 4 is detachably mounted on the output shaft of the motor. By integrally manufacturing the three blades 51 of the pressing blade 5 and detachably mounting the middle blade of the pressing blade 5 on the output shaft of the motor, the disassembly of the pressing blade 5 is convenient.

[0026] This utility model is provided with a bottom cylinder 2, an intermediate cylinder 3 and a top cylinder 11. The intermediate cylinder 3 is provided with a granulation hole 6 and the top cylinder 11 is designed in a trumpet shape. Therefore, when the granulation material is put into the top cylinder 11, the top cylinder 11 plays a certain transition role, which prevents the granulation material from falling out of the granulation hole 6 before granulation, thus avoiding the problems of material leakage and incomplete granulation.

[0027] By setting the pressing blade 5 as three fan blades 51, each fan blade 51 has a structure that is inclined downward on the side near the direction of rotation, so that the pressing blade 5 can easily cut into the granulation material when the granulation material is rotating, thus reducing resistance.
